Add Elkhart Lake to the list of the platforms that intel_pmc_core
driver supports for pmc_core device.

Just like Ice Lake and Tiger Lake, Elkhart Lake can also reuse all the
Cannon Lake PCH IPs. Also, it uses the same PCH IPs of Tiger Lake, no
additional effort is needed to enable but to simply reuse them.
